摘要： An electrosurgical unit for being capable of selection of desirable electrosurgical operation mode in cutting mode and coagulation mode. A handpiece for the operation is connected to a control means through an isolation means, and an operator performs the operations of cutting mode or coagulation mode by use of the handpiece. The handpiece is provided with a cutting mode switch and a coagulation mode switch. The operator can perform the mode change only in the sterile field by depression of these switches simultaneously.

摘要： A blood coagulating apparatus for stopping bleeding by heating the bleeding portion of the living body while producing an electric discharge on the bleeding portion. A patient plate which is capable of maintaining the state of being electrically connected to the living body is placed on the living body. An active electrode including an electrolyte ejector is brought to the vicinity of the bleeding portion. The electrolyte ejector includes an ejector for supplying an electrolyte to an air passage for passing air therethrough at a high speed so as to mix the electrolyte with air and ejecting the atomized electrolyte to the bleeding portion. The electric discharge produced in the vicinity of the bleeding portion by applying a high-frequency voltage between the active electrode and the patient plate is made stable and effective by ejecting the atomized electrolyte toward the bleeding portion. Thus, a uniform coagulation spot is formed and stable hemostatis is enabled.

摘要： A bone mineral content measuring apparatus for obtaining the bone mineral content of an object to be examined by irradiating X-rays onto the object and measuring the X-rays which have passed through the object. An X-ray generating device generates X-rays having a continuous spectrum. The X-rays generated pass through an X-ray filter before the irradiation of the object or after the transmission of the object. The X-ray filter is composed of a substance having an X-ray absorbing characteristic with the K-absorption edge at a predetermined energy value. The X-rays which have passed through the X-ray filter and the object are detected by the X-ray detector. A data analyzer inputs the detected X-ray detection data and analyzes the bone mineral content of the object on the basis of the X-ray absorbing characteristic of the X-ray filter.
